Abstract

The invention relates to an integrated separator (1) for separating coarse and fine particles in a cement making process, said integrated separator (1) comprising a static separator (2) and dynamic separator (3), said dynamic separator (3) being arranged in an uppermost position relative to said static separator (2) and said static separator (2) comprising an outer housing (11); a de-agglomeration cone (5) and a first inverted frustum cone (6), said de-agglomeration cone [5] arranged adjacent to said first inverted frustum cone (6) by holding rods (18), said holding rods (18) are connected to said inverted first frustum of cone (6).

First claim

What is claimed:

1. An integrated separator ( 1 ) for separating coarse and fine particles in a cement making process, said integrated separator ( 1 ) comprising:
a static separator ( 2 ); and
a dynamic separator ( 3 ), said dynamic separator ( 3 ) being arranged in an uppermost position relative to said static separator ( 2 ), said static separator ( 2 ) comprising:
an outer housing ( 11 );
a de-agglomeration cone ( 5 ); and
a plurality of inverted frustum cones ( 6 , 7 , 8 , 9 , 10 ) comprising a first inverted frustum cone ( 6 ), and a second inverted frustum cone ( 7 );
wherein said de-agglomeration cone ( 5 ) is arranged adjacent to said first inverted frustum cone ( 6 ) by first holding rods ( 18 ) connected to and extending between the de-agglomeration cone ( 5 ) and the outer housing ( 11 ),
wherein said second inverted frustum cone ( 7 ) is arranged below said first inverted frustum cone ( 6 ) by second holding rods ( 18 ) connected to and extending between the second inverted frustum cone ( 7 ) and said outer housing ( 11 ).

2. The integrated separator ( 1 ) according to claim 1 , further comprising a reject chute ( 12 ) configured for extracting coarse particles from said static separator ( 2 ) and a main air supply duct ( 16 ) configured for supplying air to said static separator.

3. The integrated separator ( 1 ) according to claim 1 , further comprising feeding chutes ( 4 , 4 a ) arranged on said static separator ( 2 ) and said plurality of inverted frustum cones ( 6 , 7 , 8 , 9 , 10 ) further comprising:
a third inverted frustum cone ( 8 ), said first inverted frustum cone ( 6 ) having a maximum diameter which is larger than a maximum diameter of said second inverted frustum cone ( 7 ), and said maximum diameter of said second inverted frustum cone ( 7 ) being larger than a maximum diameter of said third inverted frustum cone ( 8 ).

4. The integrated separator ( 1 ) according to claim 1 , wherein a portion of said outer housing ( 11 ) proximal to the position of said de-agglomeration cone ( 5 ), has a smaller diameter than a portion of the outer housing ( 11 ) which is distal to the position of said de-agglomeration cone ( 5 ).

5. The integrated separator ( 1 ) according to claim 1 , wherein said dynamic separator ( 3 ) further comprises a static vane ( 13 ) configured for both in-line and parallel arrangement, a rotor ( 14 ) configured for both in-line and parallel arrangement, a reject cone ( 15 ) configured for both in-line and parallel arrangement, a reject chute ( 12 ) configured for both in-line and parallel arrangement and an output chute ( 17 ) configured for both in-line and parallel arrangement.

6. The integrated separator ( 1 ) according to claim 5 , wherein said inverted frustum cones ( 6 , 7 , 8 , 9 , 10 ), said reject chute ( 12 ), and said deagglomeration cone ( 5 ) are arranged concentrically one above the other.

7. The integrated separator ( 1 ) according to claim 2 , further comprising feed chutes ( 4 , 4 a ) arranged at an upper most position relative to the deagglomeration cone ( 5 ) through which coarse and fine particles enters a static separator zone, wherein for both in-line and parallel arrangement, said air goes through said main air supply duct ( 16 ), said main air supply duct ( 16 ) being attached to said outer housing ( 11 ) at its bottom for in-line arrangement, said main air supply duct ( 16 ) being attached to said outer housing ( 11 ) at its top for parallel arrangement.

8. The integrated separator ( 1 ) according to claim 2 , wherein during separation of coarse and fine particles in a static separation zone, said fine particles are passed away by said air supplied through said main air supply duct ( 16 ), and wherein said inverted frustrum cones ( 6 , 7 , 8 , 9 , 10 ) are arranged concentrically so an annular gap acts as a fine particle carrying passage.

9. A cement plant, comprising the integrated separator ( 1 ) according to claim 1 .

10. An integrated separator ( 1 ) for separating coarse and fine particles in a cement making process, said integrated separator ( 1 ) comprising:
a static separator ( 2 ); and
a dynamic separator ( 3 ), said dynamic separator ( 3 ) being arranged in an uppermost position relative to said static separator ( 2 ), said static separator ( 2 ) comprising:
an outer housing ( 11 );
a de-agglomeration cone ( 5 ); and
a plurality of inverted frustum cones ( 6 , 7 , 8 , 9 , 10 ) comprising a first inverted frustum cone ( 6 ) arranged in an uppermost position within the plurality of inverted frustum cones ( 6 , 7 , 8 , 9 , 10 ),
wherein said de-agglomeration cone ( 5 ) is arranged such that an upper portion of said de-agglomeration cone ( 5 ) is located above an upper portion of said first inverted frustum cone ( 6 ).
